Orthopedic device for treating hip dysplasia and hip dislocation

Abstract

In an orthopedic device for treating hip dysplasia and hip dislocation, a pelvis-supporting portion is provided with two angular projections extending in the region of natural hip joints of a patient and each carrying a pivot joint including rotation discs to which a curved guide is connected. The curved guide of each pivot joint has a longitudinal slot in which an end of an upper shank guide bar is displaceable and arrestable in any desired position. Two upper shank guide bars carrying the respective upper shank supports are pivotally connected to the lower shank guide bars carrying the respective lower shank supports.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims: 
     
       1. An orthopedic device for treating hip dysplasia and hip dislocation, comprising a pelvis-supporting portion; two upper shank guide bars laterally extended from said pelvis-supporting portion and carrying upper shank supports, respectively, said upper shank guide bars having ends pivotally connected to said pelvis-supporting portion in the regions of natural hip joints of a patient and being adjustable with respect to said pelvis-supporting portion in any desired angular position; each of said upper shank supports being pivotable about the longitudinal axis of the respective upper shank guide bar and arrestable thereon in any desired position; joint means for connecting said ends to said pelvis-supporting portion; and two lower shank guide bars connected respectively to said upper shank guide bars and carrying two respective lower shank supports, the pelvis-supporting portion including two angularly extending projections extending in the regions of natural hip joints, said joint means each including rotative means being rotatable only about an axis extended perpendicularly to said respective projection and being arrestable in any desired rotation position, and a curved guide connected to said rotative means and spaced therefrom at a distance which varies over the length of the guide, the end of the respective upper shank guide bar being displaceably guided in said curved guide and adpated to be arrested in any desired position with respect thereto. 
     
     
       2. The device as defined in claim 1, wherein said curved guide is formed with a guide slot in which the end of the respective upper shank guide bar is displaceable. 
     
     
       3. The device as defined in claim 1, wherein said rotative means include two circular discs spaced from each other to receive the respective projection of the pelvis-supporting portion therebetween and clamping screws for arresting the discs to each other in any desired rotation position. 
     
     
       4. The device as defined in claim 3, wherein the axes of both rotative means include with each other an angle β of about 90°.
